Richard has been turning the internet on its ear recently with his M90 Supercharger tests. He’s built an adapter plate to run one on a 4.8 LS and has obviously been testing them on the 3.8 liter V6 as well. These little blowers make real power on the right combos and are dirt cheap if you find them at the wrecking yard. So in this test here, he’s got the same blower with the same pulleys to see just how much power this thing makes on the 3.8 vs the 4.8. Watch the video and let us know what you think, and if you might bolt one onto something you’ve got in your garage.
